21 is a factor of 63 (21 * 3 = 63).
71 is a Prime number.
Since 71 has no common factors with 63, they must be multiplied together to find their least common multiple.
Thus, the least common multiple (LCM) of 21, 63 and 71 is 63 * 71 = 4473.
The LCM is 441.
For 147, 63, 21 the LCM is: 441
For the values: 21, 9 the LCM is: 63
lcm(49, 63, 21) = 441 49 = 7^2 63 = 3^2 x 7 21 = 3 x 7 lcm = 3^2 x 7^2 = 441
The Least Common Multiple (LCM) for 21 3 9 is 63.
For 21, 63 and 167 the LCM is: 10,521
The LCM is 693.
The LCM of a group of numbers is the smallest number that all of the given numbers will divide into.The LCM will always be the largest of the given numbers or its multiple. In our case, the largest number is 77. Since 21 and 63 will not divide into 77, the LCM will be a multiple of 77. That multiple will be the number 693 (77 x 9), because: 693/21 = 33 or 21 x 33 = 693; 693/63 = 11 or 63 x 11 = 693. Thus the LCM is 693.
The Least Common Multiple (LCM) for 36 63 77 is 2,772.
The LCM is 231.
LCM OF 9,3 AND 21 IS 63. CHECK FOR YOURSELF IF YOU ARE NOT SURE.
The LCM is 441.
For 147, 63, 21 the LCM is: 441
The least common multiple is the smallest number that is multiple of two or more numbers. 21: 21, 42, 63 63: 63 The LCM of 21 and 63 is 63.
7 x 9 = 63 3 x 21 = 63 Therefore, the LCM of 9 and 21 is 63.
Until that other number shows up, the LCM is 63.
21 and 63, respectively.
